2 Claims;

This invention relates to a banding tool and more particularly to a banding tool designed for use in banding'coils of strip steel.

The principal object of the invention is the provision of an efficient tool by means of which one man can effectively position, tighten, and seal a band about a coil of strip steel.

A further object of the invention is the provision of a banding tool capable of use in banding stacksof steel sheets and various other rectangular packages.

A still further object of the invention is the provision of a banding tool in which the sealing.

die used may be readily interchanged.

A further object of the invention is the provision of a banding tool capable of tightening the banding material, effecting theseal of the banding material, and cutting the surplus band-nee essarily used in effecting the tightening operation.

The banding tool shown and described herein has been designed to provide an efficient tool for applying metal bands to coiled strip steel, in as much as a large percentage of the present day steel plant capacity comprises hot rolled strip commonly shipped in coils. At the present time most of the coils are not banded due to the ineificiency of the known banding methods and means for effecting the banding'operation, with the result that partial uncoiling of many of the coils of strip steel results in damage toseveral' feet of material of each coil which must subsequently be removed and discarded as it is marred, torn, scratched, or otherwise unsuitable for use in subsequent fabricating operations. Ihis represents a considerable waste when it is considered that the shipment of steel strip in coil form is a common practice. The trailing ends of the coils are also often damaged in intermill'shipment with the result that a considerable-waste occurs before the actual shipment of the coil. The principal object of the present invention, therefore, is to provide a banding toolwhich may be operated by one man and which will effectively andconveniently and easily apply metal bands to the coiled strip steel; tightening, sealing, and cutting off the excess band in almost simultaneous operations. The tool is particularly adapted for banding hot coil wherein the invention, therefore, comprises a tool which permits one man to' conveniently and easily place a preformed loop of banding material about the hot coil, tighten it, seal it, and remove the excess material with the banding tool which is first used as acarrier in placing the preformed band about the hot coil.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can

be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompany-- ing drawing, wherein:

Figure '1 is a top plan view of the banding tool, with parts broken away.

Figure 2 is a side elevation of the bandin tool, with parts broken away.

Figure 3 is an end elevation taken on lines 3-3' of Figure 2.

By referring to the drawing and Figures 1 and 2 in particular it will be seen that a banding tool, comprising a slightly arched base ID, has positioned upon the upper surface thereof a body member II which in turn is provided at the points adjacent its opposite ends with two rotatable shafts, one of these rotatableshafts taking the form of'a slotted tightening roll [2 adapted to receive one end of a band B, as shown in Figure 2, in the slot thereof in a manner so that upon rotation the tightener roll [2 causes the band to be tightened with respect to a loop formed by the band. In order to facilitate the easy placement or the end of the band B in the slot of the slotted tightener'roll [2, a portion l2A of the roll I 2 is cut away from the remainder and hinged thereto. This causes the tightener role l2 to form in effect'a projection positioned besidethe hinged portion IZA and spaced slightly therefrom so as to form in effect an extension of the slot in the tightene'r' role I 2. A concave section I4 is formed in the body portion H at one side of the tightener roll l2 so that the hinged portion IZA thereof can be moved sidewardly and backwardly thereinto when the tightener roll I2 is in appropriate position. As best shown in Figure 1 of the drawing'; this hinged section lZA of the roll 12 can be swungsidewardlyaway from the remainder of the roll when the tightener' roll I2 is in appropriate position andthus permitsthe endof the band B to be easily positioned in the slot. Due to the fact that the pivot I3 of this hinged section is positioned back within the body portion l I, the hinged section 12A will automatically close once the roll [2 is rotated. This action takes place because the rounded surface above the hinged section slides against the concave portion I 4 in a cam-like action as the tightener roll I2 is' revolved. The concave portion [4 of the body portion II provides space for the hinged section IZA to swing sidewardly and backwardly into. It will thus be seen that the band B, taking the form of a loop of sufficient diameter to enclose a coil of strip steel, has its opposite ends positioned in the banding tool as best shown in Figur 2 wherein one end of the band B is shown bent backwardly over a beveled section IDA of the base It, and

passed over the base I alongside the body member II and beneath a sealing die l5. The band is held in desirable position on the base Ill! and adjacent the body member H by means of a latch It the lowermost end portion of which engages the side of .the'band and which is in itself opposed by a coil spring IT. The uppermost end portion of the latch It extends above the body portion ll so that it may be moved manually to permit the rethreading of the band in the banding tool. The band passes beneath the tightener roll 12 and emerges beneath the base. as shown in Figure 2, passing through a slot like opening ,IB which is formed in an extension IQ of the base Ill. The band B, completing the loop of a size adapted to be positioned about a coil of strip steel, returns to the banding tool as indicated at B' and'passes over the opposite end of the band directly below the sealing die l5. It is held in this position by the latch I 6 and terminates after being placed in the slotted tightener roll I 2.

It will thus be observed by referring to Figure 2 that when the tightener roll I2 isrotated in a clockwise direction the band B will be tightened with respect to the coil about which it has been positioned, the banding tool itself having served as a convenient handle for positioning the band about the coil, and at such time as the band B is tightened the slotted tightener roll I2 is held against backward rotation by means of a ratchet 20 (see Figures 1 and 3) at which time the sealing die I is depressed by means of a cam 2| formed on a transversely positioned shaft 22 which comprises the other one of the two rotatable shafts heretofore mentioned. The sealing die portion of the banding tool utilizes a mechanical principle well known wherein the cam 2| will, upon rotationof the'sh'aft 22, engage the sealing die [5 and move it downwardly to effect a seal, it being desirable that a metal clip (not shown) as is commonly employed', be positioned about the band at the sealing point and the seal effected therethrough; In order that these two rotatable shafts may be rotated in carrying out the operations heretofore described in tightening and sealing the band, handles are affixed to these shafts, one of these, a handle 23. is pivoted about the slotted shaft, I2 and provided with a ratchet 24 for engaging gear teeth 25 formed upon the slotted shaft 12., In connection withthe ratchet 24 and the handle 23 there is a manual release lever 25' positioned through a portion of the handle 23 and operatively engaging the ratchet 24 so that the same can be released from engagement with the slotted shaft l2 which will then permit the handle 23 to be moved to the position indicated in dotted lines in Figure 2 of the draw ing in which position a projection 26, formed on the handle 23, engages one portion of an L shaped knife 2'! and causes the same to move outwardly so as to cut the band B which is being held under tension directly in front thereof. The knife 21 'moves sidewardly and outwardly away from the body portion ll of the tool and engages the band B and cuts it from edge to edge. It has been determined that the band usually tears after the knife has entered from one side thereof and cut a short distance. A spring 28 engages a section of the knife 21 and is adapted to return the knife 21 to its position within a slot-like opening in the body member ll of the tool wherein the L shaped knife is pivotally positioned on a pivot 21A. It will thus be observed that the tool effectively bands, tightens, seals and cuts in almost simultaneous operations, and further that the tool'itself forms aconvenient handle for supporting the loop form of the band in placing it about the coil or strip steel to be banded.

The banding tool has been designed so that it may also be used in banding flat packages as, for example, p c s of steel sheets about which the bands are applied to form an effective and efficient shipping package. In order to accomplish this purpose and provide an efiicient tool having a base of suificient length to insure against the tools tipping during the tightening operation, the base, as may be seen in Figures 1 and 2 of the drawing, has outwardly extending projections l9 and ISA formed thereon in which slot-like openings l8 and I8A permit the passage of the band as in the operation of a banding coil as shown in Figure 2 whereas in utilizing the banding tool in banding flat surfaced packages the band would remain above the extensions I 9 and HA of the base I0 so as to be on a substantially fiat plane with respect to the flat plane of the surface of the rectangular package being handed. The operation in either case is substantially the same, as the band must be tightened through the rotation of the slotted shaft 12 and the seal must be effected by the sealing die l5 and the band subsequently cut'by the knife '21. As illustrated in Figures 1 and 2 of the drawing, the sealing die 1 5 comprises a U- shaped member of an interchangeable character held in elevated relation with respect to the band passage therebeneath by means of a spring tensioned member 29 which slidably engages the shaft 22 and the cam 2!. The shaft 22 is adapted to be moved by means of a handle 30 as illustrated, which is the other one of the two handles heretofore mentioned.

Having thus described my invention, what I claim is: r
